SLIDABLE WINDOW-SASH SUPPORT.

Application filed September 7, 1926.

My invention relates to windows and has particular reference to aslidable mounting for the upper sash of the window which allows thepivoting of the said sash at its lower end, so that it may be swung intoreversed position to present the outside of the sash inwardly forcleaning or for ventilation.

The object of the invention is to provide a mounting for the upper sashof a window which will allow said window to be raised and lowered in avertical direction, but which will also allow the swinging of the upperend of the sash inwardly. It is desired to so connect the upper sashwith a movable rider or stile that the sash may be swung inwardly with aminimum of ma nipulation. It is also desired to form the connection insuch a manner that the construction will be economical to manufactureand simple in its operation.

Referring to the drawing herewith, Fig. 1 is a side elevation of awindow casing, the upper portion of the window jamb being in verticalsection approximately on the line 1-1 of Fig. 3. Fig. 2 is a sideelevation of the window sash removed from the frame of the casing, theupper sash being in reversed position. Fig. 3 is a broken trans versesection approximately on the line 3-3 of Fig. 1. Fig. d is a brokenfront elevation of the upper sash showing the rider attached thereto.Fig. 5 is a top plan view of a sheet metal rider which may be used. Likenumerals refer to like parts in all the views.

In the drawing 1 have shown a window casing 1 having a vertical channel2 for the lower sash and a similar channel 3 for the upper sash. Theimprovement constituting the invention resides in the mounting of the uper sash and attention is, therefore, called to igs. 2, 3 and d. Theupper sash 4 is mounted for attachment to riders 5, one on each side ofthe sash. These riders may be made of wood, as shown in Figs. 2, 3, andl, and in such case the sash cord may be secured to the rider adjacentthe upper end. The rider is provided with a groove 7, which, asindicated in dotted lines in Fig. d, extends only part way through therider from the inner side. A laterally projecting pin 8 at the lower endof the sash is adapted to fit within the groove 7 and to be adjustabletherein. To secure the sash to Serial No. 133,923.

the rider a plate 9 is mounted upon the upper end of the rider, saidplate having a flange 10 bent inwardly above the sash and adapted to fitclosely against the upper face thereof. On the side of the riderpresented outwardly a groove 11 is formed along the inner edge toprovide a rain pocket, the position of which will be indicated in Fig.8. This pocket is intended to catch water or moisture entering aroundthe outer side of the sash and to allow it to drain downwardly and thusguard against its entrance past the window into the room.

lVhen the sash is in upright position upon the rider as shown in Fig.4., the sash may be raised and lowered, balanced by the sash weights inthe usual manner. WVhen it is desired to throw the upper end of the sashinwardly to provide a vent at the upper end or to reverse the sash, itis released from the plate 10 at the upper end and swung inwardly, andas the upper end is moved into the room the pivotal pin 8 may be movedupwardly in the groove 7 in the rider. It will be noted by reference toeach of Figs. 1 and 2 that the upper side of the lower sash has beenbeveled orrounded upon its outer face where it is adapted to contactwith the upper sash. This beveled portion has been arranged to act as afulcrum about which the upper sash may turn or rather oscillate when itis being reversed. As the reversing movement is started the upper sashfirst bears up this beveled or rounded surface of the lower sash and thepins 8 are forced upwardly in the grooves 7. Thus a device is providedwhich tends to ease the shock in event the upper sash falls inwardly asit must fulcrum around the beveled portion, as well as the top face ofthe lower sash. This will allow the sash to be swung downwardly until itcontacts with the up per end of the lower sash 18, as shown in Fig. 2.This will give access to the outer side of the window pane for cleaning.

If desired the rider may be made of sheet metal construction throughout,and in such case the sheet metal will be bent into a tubular form, suchas is shown in Fig. 5, leaving an opening 14 in the sheet metal body 15,which provides for the rain pocket shown in the wooden construction.

The advantage of this mounting for the upper sash lies in the fact thatthe sash may be not only vertically slidable as is usual with window:sashes, but the sashvislalso allowed to be reversedto give access"to-the outside of the window sash for purposesof cleaning when desired,and thus reversal of the sash niaybe performed with little difficultyand without material change in the usual mounting of the sash. f I vIlaving thus described my invention, what I claim as new and desire 'toprotect byLetters Patent is:

3'1. A wi-ndow including a lower sash, an

' upper sash having its lower end overlapping the outer side'of saidlower sash, riders for said upper sash,'said riders having groovestherein from a point adjacent-their lower ends toabout midway of saidriders, pins at the lower end of said sash fitting slidably in saidriders whereby the upper end of said upper sash may swing inwardly tolieagainst said lower sash, for the purpose described.

2. A window including a lower sash,an upper sash having its lower endoverlapping the outer side of said lowersash, riders for said uppersash, said ridershaving grooves therein from a. point adjacent theirlower ends to about midway of said riders,;pins at the lower end of saidsash fitting sl-idably in said riders whereby the upper end of 4. In awindow construction, ran upper partially reversible sash, riders forsaid upper sashjand pins slidably connecting said IlClGTS and uppersash, a lower sash having the upper side 1 thereof beveled to form :a

fulcrum upon which said upper sash'inay oscillate.

Intestinieny whereof 'I" hereunto affix my signature this day of August,AfD. 192 6.
